Which is better, disc brake or VS drum brake?

Answer:

The principle of drum brake is that in the brake drum, the hydraulic pressure is applied to the piston of the brake wheel cylinder, and the piston rolls out the curved brake shoe

A friction material that is attached or riveted to the brake shoe, holds down the brake drum and slows the rotation of the brake drum and axle so as to achieve the purpose of braking.

In fact, sometimes the drum brake is very effective, but if you only use the brake drum tried to stop a high-speed car, you will find its limitations: it will heat attenuation, friction heat, brake drum brake shoe must lead to expansion, moving outward to come into contact with the brake drum, which means to further depress the brake pedal gas heating material produced by friction, also trapped in the internal brake shoe and brake drum, reduced braking capacity

The first braking car may stop at high speed, but luck isn't necessarily that good when it comes to the second braking.
